Bath vent fan replacement

I have a 20 yr old Broan(99110579)fan on the ceiling that doesn't work.
I turn on the wall switch and nothing moves, just hear a low
humming noise.

Not worth fixing it since a newer one would be a better option
and much quieter. I would like to buy one the same size, the hole
in the ceiling is 7 3/4 x 7 3/4, the size of the bathroom is "66x 60"
it's in the basement with no window in the bathroom, it's vented to the
outside from the fan. I don't need one with a light, any brand recommendations? Is this a DIY job for somebody like me
with little electrical work experience? thanks

Thanks, my model number is listed, however the housing dimensions are
slightly off, it's for 7 1/2 X 7 1/4" only. Then again I only measured the
outside of the hole, when I get home later I will turn the fuse off and disconnect the fan and make sure I have the right measurement.

I would be going from 50 CFM's 2.0 Sones to 60 CFM's 3.0 Sones.
Not much difference there I believe, would prefer a quieter fan(2.5 or less) but I can live with it.

The price for the upgrade kit is $54.16+$8.95 for S&H+tax, considerably less then a new unit. Best part is that it's easy to install.

Edit: After speaking with Broan customer support, I was told that my model has a housing of 8 1/4 x 8. The new ones have the 7 1/2" x 7 1/2" housing size. Oh well it lasted 23 years, time for a new fan now.

The Broan customer service dept is closed for the weekend.
I removed the old vent fan and measured the housing from the
bottom, it's 7 3/4 x 7 3/4, I didn't remove it, but I want to know
if it's bigger on the top of the housing or the same.

pinecone12, all you need is the fan. If it fits into the existing hole, otherwise, you may be best to pull out the old unit and replace with a newer one. I looked at ours, and it is a 50cfm @ 2.5 sones, but it is still pretty loud.

Ok, trying to reinstall the new motor into the old housing, I forgot how it was when I removed the old motor/fan assembly from the housing. All I know is that I have to plug in the new motor to the receptacle, but what about the wires? push them through the hole of the housing? thanks.
